众所周知，电阻式氧传感器具有温度依赖性大的缺点。我们考虑用氧离子导体作为电阻式氧传感器的新型温度补偿材料，以降低传感器输出的温度依赖性。我们还制作了氧传感器，包含钇掺杂的氧化铈（Ce0.9Y0.1O2-delta）作为一种新的温度补偿材料（TCM）和非掺杂的氧化铈作为氧分压测量材料（OMM）。此外，我们研究了氧分压依赖性和温度依赖性的传感器输出和TCM和OMM电阻。Ce0.9Y0.1O2-δ电阻的氧分压（P-O）依赖性在10（3）~ 10（5）Pa的范围内非常小，并且Ce0.9Y0.1O2-δ电阻的温度依赖性与氧分压测量材料相似。结果表明，Ce_（0.9）Y_（0.1）O_（2-δ）可以作为温度补偿材料，在1023-1273 K温度范围内，用Ce_（0.9）Y_（0.1）O_（2-δ）作为温度补偿材料的电阻式氧传感器的输出对温度的依赖性很小。(C)2004 Elsevier B.

It is well known that resistive oxygen sensors have the disadvantage of having a large temperature dependence. We thought of using an oxide ion conductor as a new temperature compensating material for resistive oxygen sensors, in order to decrease the temperature dependence of the sensor output. We also fabricated oxygen sensors that contained yttrium-doped cerium oxide (Ce0.9Y0.1O2-delta) as a new temperature compensating material (TCM) and a non-doped cerium oxide as an oxygen partial pressure measurement material (OMM). In addition, we investigated the oxygen partial pressure dependence and temperature dependence of the sensor output and the TCM and OMM resistance. The oxygen partial pressure (P-O) dependence of the Ce0.9Y0.1O2-delta resistance was very small in the range of 10(3) to 10(5) Pa, and the temperature dependence of the Ce0.9Y0.1O2-delta resistance was similar to that of the oxygen partial pressure measurement material. It was showed that Ce0.9Y0.1O2-delta could be used as a temperature compensating material, and that, in the temperature range of 1023-1273 K, the output of a resistive oxygen sensor with Ce0.9Y0.1O2-delta as the TCM had only a small dependence on temperature.
